アルミニウム合金押出加工における降伏応力の変化を考慮したときの温度上昇と押出圧力の計算
Temperature of extrusions and extrusion pressure of aluminum alloy in consideration of changing yield strength in each elements Kanji TAKEUCHI* The temperature rise and the extrusion pressure during extrusion operation are calculated by dividing billet, die, container and dummy block in to small elements. Heat transfer is calculated by the difference equation method. Heat generated are assumed as mechanical energy change to heat energy. Yield strength of metal in each elements of the billet are
